The cover member 49 b includes at least one opening 46 b that is or will be connected to the water receiving unit 20 or the water feeding unit 30. Furthermore, two channel elements can also form a tubular body, or the cover element 49 b can form a closed tube together with a channel element 49 a.

It is also conceivable to arrange the water receiving unit 20 on an infiltration ditch, for example a packed bed infiltration ditch, such that water can flow from the water receiving unit 20 into the infiltration ditch, possibly in combination with the water feeding unit 30.

The first end-side opening 44 a may include a circumferential seal 48 a. The first end-side opening 44 a may include latching elements, as shown in FIG. 2, and the second end-side opening 44 b may include mating latching regions.

The beads may protrude into the water discharge unit 40, the tubular body 42, and the half-shell bodies 42 a, 42 b, respectively. The beads may extend from edge portions of the half-shell bodies 42 a, 42 b toward a circumference of the water discharge unit 40. The beads can be tapered, converging, and/or conical, such that they eventually taper out. Their thickness or height and/or width can decrease from the edge area. Their thickness or height and/or width can be adjusted to the wall thickness. Thus, the half-shell bodies 42 a, 42 b can be stacked into each other vertically and/or without a lateral offset. This allows to minimize the stacking height, a required floor space, and/or to reduce a risk of damage.

The tubular body 42 may comprise two half-shell bodies 42 a without the openings 46 b. Thus, water drainage can be realized via areas without water receiving unit(s) 20.

The other water discharge units 40 a are substantially the same as the water discharge unit 40 described with reference to FIG. 2. The other water discharge unit 40 a comprises a tubular body 42 comprising a first end-side opening and a second end-side opening and openings 46 b, 46 b′. The tubular body 42′ may comprise two half-shell bodies 42 b′, each having openings 46 b, 46 b′. The first end-side opening may comprise a circumferential seal. The other water discharge units 40 a and the water passage units 50 can be arranged between the water receiving units 20 or, as shown in FIG. 16, between the water feeding units 30 and the water discharge units 40.

Alternatively, the water discharge unit 40, which is located at the bottom, may comprise a tubular body 42 comprising two half-shell bodies 42 a without the openings 46 b. Thus, water drainage can be implemented without a connection to the other water discharge unit 40 a, which is located above.

For example, the plurality of half-shell bodies may pass through rods or tubes attached to the support 100.

FIG. 26 shows an enlarged perspective top view of the second half-shell body 42 b according to the embodiment of the invention. The second half-shell body 42 b includes the second end-side opening 44 b and the opening 46 b disposed on the second half-shell body 42 b.

Referring to FIG. 23, FIG. 27 shows an enlarged perspective view of the second end-side opening 44 b of a tubular body 42, 42′ according to the other embodiment of the invention. The tubular body 42, 42′ comprises two half-shell bodies 42 a, 42 b, 42 b′ joined together to form the tubular body 42, 42′. The two half-shell bodies 42 a, 42 b, 42 b′ may be interlocked with each other. The ribs of the two half-shell bodies 42 a, 42 b, 42 b′ are latched with each other, such that the two half-shell bodies 42 a, 42 b, 42 b′ can stably form the tubular body 42, 42′.

FIG. 28 shows a perspective view of a supporting unit 60 according to the embodiment of the invention. The supporting unit 60 comprises an area 64 for receiving the water discharge unit 40, i.e., the tubular body 42, 42′.

FIG. 35 shows a perspective view of a supporting unit 60 according to another embodiment of the invention in a first, unseparated state. The supporting unit 60 includes a first bearing member 66 a and a second bearing member 66 b for receiving the water drainage assembly 40. As shown in FIG. 35, the first bearing element 66 a may be a first side element and the second bearing element 66 b may be a second side element. The first bearing element 66 a and the second bearing element 66 b may be mirror images of each other, as shown in FIG. 35.

The first bearing element 66 a and the second bearing element 66 b may comprise connecting means and/or latching means, such that they may be connected and/or latched together. The connecting means and/or latching means of the first bearing element 66 a and the second bearing element 66 b may be configured as a first connecting element 68 a and a second connecting element 68 b. The supporting unit 60, i.e., the first bearing member 66 a, the second bearing member 66 b, the first connecting member 68 a, and the second connecting member 68 b, may be integrally formed, for example, by an injection molding process or plastic injection molding process. In this respect, the first connecting element 68 a can be arranged and manufactured within the first bearing element 66 a and the second connecting element 68 b can be arranged and manufactured within the second bearing element 66 b to save space.

FIG. 36 shows a perspective view of the supporting unit 60 according to the other embodiment of the invention in a second, separated state. If necessary, e.g. to facilitate installation of the water discharge unit 40 into the supporting unit 60, the first bearing element 66 a and the second bearing element 66 b may initially be separated from each other. Further, the first connection element 68 a can be separated from the first bearing element 66 a and the second connection element 68 b can be separated from the second bearing element 66 b.

FIG. 37 shows a perspective view of the supporting unit 60 according to the other embodiment of the invention in a third, prepared state. The first connecting element 68 a can be “releasably” or “non-releasably” connected to a first receiving area of the first bearing element 66 a, as shown in FIG. 37, for example by insertion, sliding, gluing and/or snapping. Accordingly, the second connecting member 68 b may be “releasably” or “non-releasably” connected to a second receiving area of the second bearing member 66 b. In this context, a “releasable” connection is understood to be a connection that can be released without damage and/or destruction, and an “non-releasable” connection is understood to be a connection that cannot be released without damage and/or destruction.

For renewed, or first-time, connection of the bearing elements 66 a, 66 b, the first connection element 68 a can now be connected or latched to a respective connection area and/or latching area of the second bearing element 66 b, the second connection element 68 b can be connected or latched accordingly to a respective connection area and/or latching area of the first bearing element 66 a.

FIG. 38 shows a perspective view of the supporting unit 60 according to the other embodiment of the invention in a fourth, connected state. Now the side elements 66 a, 66 b can enclose the water discharge unit 40 (not shown).

FIG. 30 shows a perspective view of a drainage system 1 comprising water receiving units 20, water discharge units 40 and supporting units 60 according to the embodiment of the invention. The supporting units 60 support the water receiving units 20 and water discharge units 40. The drainage system 1 may further comprise alignment units 70. The alignment units 70 are described below with reference to FIGS. 31-33. The supporting units 60 may also support the alignment units 70.

FIG. 31 shows a front view of a drainage system 1, further comprising alignment units 70 according to the embodiment of the invention. The alignment units 70 extend, as strain aids, along the water receiving units 70. They can be used during an assembly or installation of the drainage system 1 for aligning and/or fixing the drainage system 1 and particularly the water receiving units 70.

FIG. 32 shows an enlarged perspective view of the drainage system 1, further comprising the alignment units 70 according to the embodiment of the invention. The alignment units 70 can be designed, for example, as L-profiles, S-profiles, or Z-profiles. The alignment units 70 may include openings 72, such that a mass of the alignment units 70 may be reduced and/or a distribution of surrounding material such as sand, gravel, concrete, or bitumen may be facilitated. The alignment units 70 may include latching elements 74, such that connection to the water receiving units 20 and/or water discharge units 40 can be facilitated. The alignment unit 70 may be adapted to the supporting unit 60.

FIG. 33 shows an enlarged perspective view of an alignment unit 70 according to the embodiment of the invention. The alignment unit 70 may be aligned with the water receiving unit 20 and/or cover unit 10. To this end, the alignment unit 70 can include, for example, openings or recesses that provide space for the latching areas 19 of the cover unit 10 and the latching elements 29 of the water receiving unit 20 and/or the guide pins and recesses of the cover unit 10.

FIG. 34 shows a perspective view of a drainage system 1, further comprising a cast body unit 80 according to another embodiment of the invention. The cast body assembly 80 may comprise concrete and the elements of the drainage system 1. The concrete, from one side or both sides of the water receiving unit 20, can be deposited into the neck piece spaces 24 a to enclose each of the neck pieces 24. Alternatively, or in addition, the concrete may, for example, be stored in openings in the supporting unit 60 and/or the alignment unit 70. This allows the drainage system to be prefabricated in sections, reducing on-site labor and/or time.

Example 1

The drainage system comprises one or more single-piece or multi-piece upper members 20, such as shown in FIG. 1, and a two-piece or multi-piece lower member 40, such as shown in FIG. 2, which together form a drainage channel element 1, such as shown in FIG. 3. The drainage channel element 1 can also have an inlet frame or grate 10, as shown in FIG. 7, to receive the water and ensure that the channel can be walked on and driven over. The components of the drainage channel element 1 have various technical features and resulting advantages.

Single-Piece or Multi-Piece Upper Part (without Additional Pipe Section)

In this variant of the upper part 20, individual neck pieces 24 are inserted into the corresponding receptacles 46 b of the lower part 40. The neck pieces 24 can be removably secured in/to the receptacles 46 b of the lower portion 40. This can be achieved via a clip-on connection and/or screwed connection. Dividing the drainage channel element 1 into upper part 20 and lower part 40 has the advantage that it can be disassembled and stacked for transport and storage and, if necessary, to save space at the construction site, thus reducing the space required in the aforementioned areas. Another advantage is that a more manageable component is available for assembly, e.g. height alignment, on the construction site due to the strength and latchability of the upper part 20. Another advantage is easier sealability, since there is only one sealing plane which must be sealed for the upper part 20 and the lower part 40. In the case of a vertically split upper part, for example, two sealing planes perpendicular to each other would have to be taken into account, wherein particularly the transition area between two sealing planes (horizontal and vertical in this case) would be extremely difficult to seal.

The uppermost part of the upper part 20 is formed by a longitudinally extending channel 22. Within the channel 22, transverse ribs 28 are provided at the apex of the arches to stiffen the channel 22, but also to prevent water from standing in the area of the arch. This could happen if the ribs 28 are not arranged at the apex of the arch. The ribs 28 also have a recess in their upper region which prevents the water from flowing from one rib 28 to the other in the case of neck pieces 24 or inlet cross sections which may be blocked by dirt, for example.

In the lower area of the neck pieces 24, these have a circumferential rim area, as a height stop and abutment for the clip-on connection and/or screwed connection. The diameter of the neck pieces 24 is configured to match the available standard diameters of the pipes, e.g. according to DN 75, 100, such that the neck pieces can be combined with standard pipes and/or standard pipe seals. The receptacles 46 b may have a circumferential bevel to facilitate insertion of the individual neck pieces 24 of an upper part 20 into them. Stiffening ribs can be provided in the lower area of the neck pieces 24 to increase lateral rigidity.

The grate 10 is placed onto the channel 22 arranged above the neck pieces 24. The grate may be made of cast iron and/or have at least one recess 19 on its side surfaces corresponding to respective latching projections 29 of the upper part 20. Thus, the grate 10 is releasably attached to the upper part 20. The latching projections 29 also center the grate 10 in all three axes. This particular configuration of the latching projections 29 has the advantage that different grates 10 can be placed onto the upper part 20. In this case, the grate sides may not engage the latching projections 29, but may extend into the clearance of the latching projections 29 and rest on the upper edge of the upper part 20.

Position securing means are provided at the respective end faces of the grate 10 or the frame. One end face of the grate is provided with startup bevels and longitudinally extending positioning pins which interact with positioning pockets provided on the opposite end face. The positioning pockets have a pin section at their ends facing away from the end face. The startup bevel of the opposite end face interacts with the pin sections when two grates 10 are joined. As a result, positioning in two axes is achieved, as shown in FIG. 8 et seq. At least one projected rib 14 extending in the longitudinal direction of the grate 10 is provided on the bottom side of the grate 10 to direct incoming water into the channel 22 and prevent the water from running horizontally past the bottom side of the grate 10 and past the channel 22 due to its surface tension.

Advantageously, the outer width of the projected ribs 14 is greater than the width of the channel 22, such that, when the grate 10 is placed, the bottom side projected ribs 14 move the outer channel edges apart, providing a bias between the projected rib 14 and the outer channel edge. Furthermore, the upper edges of the channel are supported on the projected ribs of the grate against a pressure arising during concreting.

The side walls of the grate 10 have draft angles at their ends which allow the visible surfaces of the grate 10 to abut without gaps.

The upper parts 20 each have different end faces 22 a, 22 b that interact with each other during connection. One end face 22 a has a pin portion that has latching means on its side and/or bottom that engage complementary latching means on the other end face 22 b and compensate for tolerances, such as manufacturing tolerances and temperature-induced length changes of different materials, in the longitudinal direction. The lateral latching means ensure centering in the transverse direction. Overall, the latching means are configured in such a way that the two upper parts can be moved with a certain increased force, even if the latching means are “latched.” For the final fixation of the two upper parts 20 to each other, a screw can be inserted into a respective recess on the bottom of the pin side in the upper part of the other side (pocket end). The latch can then no longer be released due to the contact pressure of the screw. A plurality of downward parallel ribs is on the bottom side of the end of the pocket. These ribs are to prevent workers who have connected two drainage channels by screwing from injuring themselves on the screw that protrudes downward. At the end of the pin piece, there is also a cross rib that can be overflowed, which also causes stiffening for the side walls of the channel 22. A gap-free connection between the grids 10 can be ensured by adjusting the length with the latching means. Thus, it is also possible to create a longer gutter line without gaps between the top edges of the grates 10, since each drainage element 1 offers the possibility of compensating for length tolerances.

The spacing of the arches of the upper part 20 is different. In this case, the spacing corresponds to a distance of 100 mm or an integer multiple thereof, such that steel reinforcement mats commonly used worldwide can be inserted in the gaps. Due to the multi-part nature of the drainage channel element 1 with separate upper part 20, the reinforcement mats can advantageously be inserted from above.

Upper Part with Additional Pipe Piece

Advantageously, pipe sections 30 of standard pipes, e.g. according to DN 75, 100, can be inserted between the upper part 20 and lower part 40. The pipe length can be cut on site as required. It is therefore possible to combine the drainage channel element 1 with standard pipes.

The standard pipes already have a seal that can also be used to seal between the neck pieces 24 and the pipe sections 30. The diameter of the neck pieces 24 is matched to the seals of the pipes in such a way that when the neck pieces 24 are pushed in, a fixation is achieved in addition to the sealing. Additional fixing means are not necessary. On the construction site, it is advantageous to install such drainage channel elements as deep as possible in the soil, such that the vertical loads (vertical pressure, compressive stress) are reduced by the conical spread with increasing depth, since the area over which the load is distributed increases with increasing depth, as shown in FIGS. 4 and 5. Therefore, in this case, it is advantageous to use individual pipe sections 30 that can be cut to length. With pipe sections 30 of different lengths, slope situations can be represented easily and yet fixed in height, and individual overall heights can be achieved. Furthermore, the amount of concrete required for load transfer can be significantly reduced by a particularly deep installation and the resulting low vertical loads.

Two-Piece Lower Part

The two parts 42 a, 42 b of the lower part 40 are substantially identical, except that the upper part 42 b may include openings and/or receptacles for the neck pieces 24 and seals, if any. Advantageously, the individual parts 42 a, 42 of the lower part 40 are stackable for transport and storage, as shown in FIGS. 24 and 25.

The connection of two parts (upper piece 42 b and lower piece 42 a) of the lower part 40 to each other is as follows: a groove extending in the longitudinal direction of the channel is formed on one side wall (right side, see FIG. 20). A sealant 48 c, for example a round foam rubber cord, can be inserted into this groove. In the area of the groove base, an elevation is provided which also runs in the longitudinal direction of the channel and applies a linear pressure load on the sealant, particularly when both halves 42 a, 42 b are joined together, thus ensuring a secure seal. On the opposite side (left side, see FIG. 19), there is a surface which also extends horizontally in the longitudinal direction of the channel and which, analogously to the opposite side (right side), also has an elevation extending in the longitudinal direction of the channel, such that, if the two parts are assembled, a linear pressure load is applied to the sealing means 48 b, 48 c on both sides, thus ensuring an even more secure seal. It is possible that the surface also has a collar running in the longitudinal direction of the channel to give the sealing geometry additional rigidity, especially against deformation as a result of vertical force application.

In addition to the sealant, the component also has vertically aligned fasteners, for example clips that counteract vertical pulling apart, and domes and pockets that counteract horizontal shifting and twisting. It is further possible to provide the domes and/or pockets with additional latching means to prevent the joint area between the upper piece 42 b and the lower piece 42 a from deforming and leaking under horizontal load.

Another advantage is that the joint area is identical to the fasteners and can be joined in only one way. As a result, it is easy to connect the upper piece 42 b and the lower piece 42 b. In addition, two bottom sections 42 a (without openings) can be joined together to form a closed pipe cross-section to implement areas where neck sections 24 are not required for drainage. So it is possible to stay in this drainage system without using other pipes. Thus, both continuous slots and interrupted slots are possible in the surface to be drained. It is also possible to use a plurality of point drains above the standard pipes if the longitudinal channel is omitted.

Advantageously, the upper piece 42 b and lower piece 42 b are substantially identical. One difference is the flange area of the upper piece 42 b with the row of openings 46 b to the neck pieces 24. This is an advantage because both parts 42 b, 42 a can be produced with interchangeable inserts from one injection mold. Alternatively, the openings 46 b can be made subsequently, even at the construction site. This can reduce production costs.

On both longitudinal flanks, the lower piece 42 a and/or upper piece 42 b have a plurality of pins as shown in FIG. 21, as well as a plurality of pockets on the other side. Alternatively, pins and pockets can alternate on both sides.

In addition to the connecting means, the upper piece 42 b and lower piece 42 a have other special features.

The upper pieces and/or lower pieces can be easily stacked as shown in FIGS. 24 and 25. This reduces costs during transport and storage. It is not necessary to stack only upper pieces 42 b or only lower pieces 42 a. Advantageously, upper pieces and lower pieces can also be stacked one below the other or alternately.

In order to achieve the lowest possible stacking height with geometric rigidity, the upper pieces 42 b and lower pieces 42 a have inwardly projecting beads only in the side wall area. The beads have two functions: first, the beads provide geometric stiffening for the two pieces 42 b, 42 a, and second, the beads enable the low stack height by engagement.

In addition, the parts 42 b, 42 a have outwardly projecting support feet in the side wall area extending into the lower area, which can also be stacked very flat inside each other and/or on top of each other. In this way, a smooth and shock-free (dense) area can be created in the lower section of the lower piece 42 a, which is also camera-accessible and easy to clean. A smooth surface results in less buildup and a higher flow rate.

The surfaces running horizontally in the longitudinal direction give the component greater longitudinal stiffness when loaded in the longitudinal direction.

To ensure that the bottom of the lower part 42 a, or the top of the upper part 42 b, is smooth yet stable, the beads are designed as ribs on the outer sides of the lower part 42 a, or the upper part 42 b.

Advantageously, these ribs in this area do not interfere with stacking, since they are adjusted to the stacking height. The minimum stacking height depends on the material thickness and the radius of the semicircular base structure. In the cross-section of the channel body, the ribs are crescent-shaped, running softly into the side wall in the direction of the joint area. This allows the minimum stacking height and provides uniform rigidity over the entire body of the lower part 42 a, or upper part 42 b. Where the ribs become flatter and/or weaker, the pockets become firmer and stiffer.

To further optimize longitudinal rigidity, the lower piece 42 a, and the upper piece 42 b in partial sections, have exactly one longitudinal rib centrally on the outer side, which does not hinder concreting of the drainage channel element 1; the concrete can flow from two sides up to the longitudinal rib. This counteracts the formation of unwanted air bubbles in the concrete.

The connection of several drainage channel elements 1 has special features. The upper portion 42 b and lower portion 42 a each have a socket end 44 a and a tip end 44 b. The socket end 44 a may include at least one latching element. The latching elements are positioned on the periphery of the lower part 42 a and upper part 42 b, respectively, and engage respective latching surfaces of the tip end 44 b. Advantageously, the latching surfaces, analogous to the latching elements of the upper part, can be used to compensate for length tolerances during assembly of the drainage channel elements 1.

Further, the socket end 44 a includes at least one insertion aid that allows the tip end 44 b to easily slide into the socket end 44 a. For this purpose, a startup bevel is formed at the end of an insertion aid.

The tip end 44 b has partially circumferential flared insertion aids with a stiffening effect at its end. These insertion aids are not provided on the base or upper part so that the smooth surfaces are not disturbed in terms of flow. The inner surfaces of the tip end 44 b have parallel ribs, as shown in FIG. 27, which both increase rigidity in this area and prevent inward slippage of the side walls. The rib ends extend beyond the flanks of the tip end 44 b beyond the dividing plane of the component, such that, when the upper part 42 b and lower part 42 a are joined and the tip end 44 b is inserted into the socket end 44 a, the contact surfaces of the tip end 44 b do not slip against each other. A circumferential seal 48 a is insertable into the socket end.

A plurality of connected upper portions 42 b and lower portions 42 a may be arranged one above the other and interconnected, as shown in FIG. 17, such that the flow of water may be from one portion to the next.

A circumferential, angularly set-off crown area on both end faces of a drainage channel element 1 is also possible. This has the advantage that a barrel ring makes it very easy to connect two drainage channel elements to each other. In addition, due to its width, the barrel ring offers the advantage that temperature-related, material-related, and/or manufacturing-related length tolerances can be compensated by a selectable or adjustable barrel ring width, while the overall system remains tight. In addition, the barrel ring also allows the drainage channel elements 1 to be laid horizontally in radii or curves and, for example in the case of terrain curvatures, vertically, or both at the same time. A sealant or gasket applied to the inside of the barrel ring can ensure a watertight connection between the individual drainage channel elements 1.

Alignment Aids

Foot for Alignment and/or Anchoring

A foot 60 can be arranged at any point on the drainage channel element 1. For this purpose, the foot 60 can be designed in one piece or in several pieces. The foot 60 has an inner contour that corresponds to the outer contour of the channel body 42. The foot 60 may be frictionally or positively connected to the channel element 1. It is also possible for the foot 60 to be formed in one piece or in a material-locking manner with the drainage channel element 1. In this way, the foot 60 can be molded on as well. Anchoring means are arranged in the lower region of the foot 60, which, on the one hand, allow the concrete to flow through and, at least in the region of the contact surfaces, have an enlarged surface for a secure footing and for anchoring.

In addition, as shown in FIG. 29, the enlarged surface in the foot region can be used as a stacking aid.

A plurality of openings is also provided in the upper region of the foot 60 to allow concrete to flow therethrough. In addition, recesses or cylindrical recesses can be provided in the upper area, into which an alignment means and/or support means can be inserted, which enables easier adjustment and fixing of the infeed area, especially in the height-adjustable version.

Straining aids 70 can be arranged on one or both sides in the upper area of the drainage channel element 1, which allow the drainage channel elements 1 to be aligned and fixed to each other in all directions during the installation phase. The straining aids 70 can be cast as well. The straining aid 70 can be manufactured, for example, as a roll-formed profile made of sheet metal. This profile is advantageously less limited in length. The straining aid 70 can be configured as a Z-profile. In this case, a lower leg of the “Z” can rest on the foot 60 and/or the alignment aid and support aid 70 and be fastened there, for example with screws that are screwed through recesses in the straining aid. In this way, the longitudinal alignment (horizontal alignment) can be easily performed.

An upper leg of the Z-section forms the upper stop for the grate 10. If thickness variations occur due to manufacturing tolerances, tabs 74 in the center piece of the Z-section can be bent inward and, due to the inclined position of the center piece in the Z-section, press the leg of the grate 10 upward against the stop of the upper leg of the Z-section. In this way, height alignment (vertical alignment) can be easily performed.

The straining aid also has the function of enabling the gap closure between the individual grates 10. When the straining aid is applied, tabs arranged on the upper leg of the Z-section bend, thus ensuring that the grates 10 rest against each other without a gap in the longitudinal direction.

The straining aid further includes a plurality of recesses 72 to allow concrete to flow therethrough and anchor the Z-section to the structure.

Prefabrication

The drainage system 1 can be assembled at the factory into individual drainage channel elements, which are prefabricated in a casting mold with concrete to form a ready-to-install block. This allows the drainage system 1 to be delivered to the construction site in a pre-concreted condition. This allows time-saving installation of the elements, for example on a taxiway or runway of an airport, on logistics areas, on squares, for example parking lots, or on roads, for example freeways. This can reduce the downtime due to the necessary setting time of the concrete. In this variant, the use of tip ends and barrel rings is dispensed with, as a circumferential seal, for example a sealing compound such as Dichtfix, is applied directly to the joint area. Pretreatment of the sealing surface may be necessary. Advantageously, this variant allows replacement of individual elements, for example after damage.

Example 2

Even without independent traffic load bearing structures, a drainage system can be an integral part of an area to be drained.

In this case, the load transfer of the surface is not interrupted by drainage elements, but the drainage elements are selected in such a way that they have only a minor interfering effect in relation to the entire surface, e.g. asphalt surface or concrete surface. The drainage element thus becomes an integral part of the surface.

For this purpose, the drainage element is divided into a substantially vertically extending, only slightly interfering water receiving element 20, an optional water feeding element 30, and a water drainage element 40 extending substantially horizontally, or at a slope, in the ground.

Water Receiving Element

The water receiving element 20 may be, for example, a drainage channel (linear drainage), a simple open channel, or a point drain (point drainage). The water receiving element 20 only has the function of receiving the water. In this case, the water receiving element 20 feeds the received water to the water feeding elements 30 or water discharge elements 40. In the area of the surface, the water receiving element 20 may have a cover, for example a grate 10. The water receiving element 20 should not exceed a specific maximum installation depth. The maximum installation depth is determined in such a way that any weakening of the soil structure is statically only marginally relevant, since it is canceled out by the design-related safety factors, for example the Guidelines for the Standardization of the Pavement of Traffic Areas (RStO). Thus, the water receiving element 20 remains an integral part of the surface. Alternatively, the water receiving elements 20, for example manhole covers with frames, can be integrated into the traffic surface, for example suspended according to the Bituplan principle, such that no loads are passed on to the water discharge elements 30 or water discharge elements 40. Thus, even in this case, the water receiving element 20 remains an integral part of the surface.

Water Feeding Element

In the simplest case, the water feeding element 30 may be formed by at least one hollow tube or the like extending into a water drainage element 40. It is also possible for the water receiving element 20 and the water feeding element 30 to be integrally formed. To do this, for example, a hollow tube can expand upward to form an elongated water receiving slot at the surface. The spacing of the water feeding elements 30 is determined in such a way that any weakening of the soil structure is statically only marginally relevant, since it is canceled out by the design-based safeties, for example RSTO. The static principle of the bending beam or girder applies. Thus, the water feeding element 30 also remains an integral part of the surface. When designing the system comprising water receiving element 20 and water feeding element 30, care must be taken to ensure that in total the safeties are not completely used up. The water feeding element 30 may be telescopic or telescoping in design and/or comprise multiple parts. The water feeding element 30 may be sealed with respect to the water discharge element 40.

Water Drainage Element

The water drainage element 40 is installed at a depth at which the soil is capable of receiving the occurring load at rest and conducting it around the water drainage element 40. The depth required for this is determined by the load to be transferred and the nature of the surface and the soil using the respective load transfer cones (see FIG. 5). To ensure the load-bearing capacity of the load cone, the contact area on the adjacent soil stratum of the load cone must be sufficiently large. In this case, the load cone must have a sufficient footprint on the adjoining soil stratum, such that the adjoining soil stratum can receive the loads in the static rest condition.

In the area where the soil can transfer the load in the static rest condition according to a load transfer angle, a dome formation begins to occur above the cavity where the water drainage element 40 is located. The dome thus protects the water drainage element 40 from the load inputs at the surface. In the area below the dome, it is advantageous to use a waterdrainage element 40 that only needs to have a low static load-bearing capacity, for example a simple pipe with a small wall thickness. The water feeding elements 30 may extend into the water discharge element 40 while remaining movable in the vertical direction. The water drainage element 40 may have a gradient, if necessary. For this purpose, the water feeding elements 30 can be freely displaced in the water discharge element 40, preferably in the vertical direction. This can further simplify the installation of the system. Settlements, for example due to ground movement and/or changes due to frost and no frost, thus have no effect on the drainage system or on the surface. Since the water receiving element 20 is an integral part of the surface, it cannot grow out of the surface. The cause of growing out is that the drainage element maintains its position and the surrounding soil or pavement is recompacted. Even asphalt surfaces can recompact themselves by up to 2%.

The following overview shows exemplary distances or installation depths, from the surface to a top edge of the water drainage element 40, of the water drainage element 40 depending on the diameter of the water drainage element 40 according to RStO Asphalt and RStO Concrete. This results in the minimum (min.) distances for RStO Concrete, load class 100 (BK 100) and the maximum (max.) distances for RStO Asphalt, load class 0.3 (BKO.3).

This results in a direct combination of the technical properties of the drainage element with the soil conditions actually prevailing on site. This makes it possible to eliminate additional supporting structures for load transfer, for example concrete foundations, which are arranged at least below the drainage elements to ensure adequate load distribution and prevent the drainage elements from suffering damage, for example cracks or breakage, or leaving their installation position in the event of a load.

This results in reduced material usage for the drainage element. In addition, the construction effort, for example, the amount of concrete used on site, is reduced, and the setting time on site is shortened. Saving concrete and its transport improves the CO₂ balance. There are no settlement phenomena due to post-compaction in the various layers, for example pavement layers and soil layers such as non-grown soil.

Rework, such as application of a new asphalt layer, can be eliminated. Elimination of raised drainage elements can improve drainage. This can reduce a risk of aquaplaning. Furthermore, during snowfall, for example, the risk of the drainage elements being damaged by snow blades of snow plows and then having to be replaced can be reduced. In addition, the side walls of the drainage elements are subjected to less static/dynamic load, such that the risk of breakage of the side walls can be reduced.

The features of the examples can be freely combined with each other.
